Maze. This example shows the fish swimming through a simple maze. The motion path was scripted in advance. It contains a lot of vertical motion, for which there are far fewer samples available than for horizontal motion. The computation time is approximately 100x real time on a Intel Pentium II 450 MHz processor. The motion is smooth and looks mostly natural. The fish deviates from the scripted path by up to a half of its length.
Interactive fish. Here the fish is made to follow the red dot which is controlled interactively with the mouse. We use precomputed cost functions for the eight compass directions and insert five motion-constraint-free frame transitions when the cost function is changed.
Fish tank. The final animation combines multiple video textures to generate a fishtank. The fish are controlled interactively to follow the number outlines, but the control points are not visible in this animation. Animations like this one are easier to create using the scripting technique presented in this paper, because interactive control requires the user to adapt to the delays in the sprite response.
